Third-Party Integrations in MCP for Blender

MCP for Blender integrates with Poly Haven, Sketchfab, Poly Pizza, Hyper3D Rodin, and Hunyuan3D for assets, textures, HDRIs, and AI-generated 3D models.

MCP for Blender connects to five external services that extend what you can create. Each integration is opt-in and enabled via checkboxes in the MCP for Blender sidebar panel.

Available Integrations

Poly Haven

Free HDRIs, textures, and models under open licenses. No API key required.

Sketchfab

Realistic downloadable 3D models from a large creator community. API key required.

Poly Pizza

Over 10,600 free low-poly models perfect for games and stylised scenes. API key required.

Hyper3D Rodin

AI 3D generation from text prompts or images. API key required.

Hunyuan3D

Tencent AI 3D generation from text or images. API key required.

Enable each integration individually in the MCP for Blender sidebar panel inside Blender's 3D viewport. The tools for every integration are always listed in your AI client; each has a status tool (for example get_sketchfab_status) that tells the AI whether the integration is currently enabled.

Enabling an Integration

  1. Open the MCP for Blender panel

    In Blender's 3D viewport, press N to open the sidebar, then click the MCP for Blender tab.

  2. Check the integration you want

    Find the integration checkbox (for example, Poly Haven, Sketchfab, or Poly Pizza) and enable it.

  3. Enter credentials if required

    For services that need an API key, paste the key into the corresponding field. Keys are saved persistently in Blender's addon preferences.

You can also set API keys via environment variables in the environment Blender is launched from (not in your MCP client config, since the Blender addon reads them): BLENDERMCP_SKETCHFAB_API_KEY, BLENDERMCP_POLYPIZZA_API_KEY, BLENDERMCP_HYPER3D_API_KEY, BLENDERMCP_HUNYUAN3D_SECRET_ID, BLENDERMCP_HUNYUAN3D_SECRET_KEY, and BLENDERMCP_HUNYUAN3D_API_URL.
